Letters Patent No. 99,392

, dated February 1, 1870.

IMPROVEMENT IN TOOLS POR TONG-UING- AND GROOVING.

To all whom it may concern.-

Beit known that I, EDWARD F. BEUGLER, of Williamsport, county of Lycoming, and State of Pennsylvania, have invented a new and improved Set of Tools for longuing and Grooving Boards for Flooring, or other similar purposes; and I do hereby declare that the following' is a full an'dexact description thereof', reference being had to the accompanying drawings and to the letters ot" reference marked thereon.

The nature ot' `my invention consists. in making tongue and groove. tools with beveled cutting-edges, and so arranged, 'asA regards Asaid edges, that the same are competent to execute 'the work in a more perfect manner-than when performed by the tools now in common use.

To enable others skilled in thc art to make and use my iuventoml will proceed to describe its construction and operation.'

The tools used for-grooving aretshown in Figures 1, 2, 3, 4, 5, and 6,' figs. 5 and 6 showing sections ofthe same, while the tonguing-tool is shown in Figures 7 5 and 8, and iu the section designated as Figure 9.

Thesetools are made from steel, ofthe proper width, thickness, and length, in which, by means of any suitable means, the grooves E E, iigs. l and 2, are cut on both sides, tothe desired depth, leavinga rib, B, in the center, and ribs 6 6 (i6 on the edges of each side, which ribs may be finished as desired.` f

The center rib B, ou the front side of the tool, or,

.in other words, on the cutting side, is made bevel in its whole length, as shown at B B', iig. 5, the one rib being beveled from light todeft, fig. 5, the other rib being beveled from lett to right,1ig. 6, by which it will be seen that the groovng tools are in pairs, or are right and-left. The beveled cutting-edges, as seen at A2 B2, are for the purpose of cutting the sides of the groove clean and smooth, and by which means I do not leave'the broken libres ofthe wood in the groove, as is the case whelu the ordinary tool, having its edge straight, is use Then, again, a. tool, having its edges as desclibed, will remain sharp much longer than if the edges are straight,`fo,r very obvious reasons; and then experi- `a more. perfect manner, thus savinga great -amount of time; I

It will also be seen, that with cutting-edges directed as shown, the amount of power demanded must be much less to achieve the saine results, and at the saine time the board is not liable to be splitor spoiled, provided the glain should not be straight when the beveled tool is used, for it .cuts clean and smooth, while the straight-edged tool tears.

It will also be apparent thatutlhe tool, wh'en cooling in contact with knots, Ste., is not so easily broken.

The tcngnngftool, tigs.v7, 8, and S), is made in` substantially the sinne vi.iy as the one already described, except that the ribs'lO 10 are divided on the back side by a single narrow groove, which `correspoxuls exactly to the width of the tongue, and ou the opposite side must be a single rib, resultingfroln the said `grooves.

By meansof the grooves, it will be seen thatl have a xnuchlighter tool, and one which, as thc tool wears, the cntting-edges are more easily repaired. and the amount of filing t-o be done must be greatly diminisbed, thcreby saving labor as well as liles.

It will be noticed, that in n iy tonguing-tool, I present to the edge of the hoard an eut-irecuttingurlhce, and so absolutely obviate. tearing np the wood, and leaving the tongue rough, as is the case with the tools nowin use.

Having described my invention in its construction and operation,

What I claim, and for which I desire Letters Patent to issue, is-' i rlhe touguling and grooving-tools O andB, when con'- structed substantially as shown and described, for the purposes specified.

E. F. BEUGLER.
